In this article, we are going to give a brief explanation on how to implement “Home and Industry Safety using Fire and Gas Detection System using GSM”. The main aim of this project is to monitor for liquid petroleum gas (LPG) leakage to avoid fire accidents, providing house/industry safety feature where the security has been an important issue. The system detects the LPG leakage using a gas sensor and flames by a flame sensor that alerts the consumer about the gas leakage by sending SMS with the help of GSM module which is connected preprogrammed microcontroller.
Embedded Software is a key element in every embedded project that is used to run the micro-controller to perform the desired operations. In our daily life, we frequently use many electronic devices such as washing machines, refrigerators, mobile phones, security system, digital camera so on which will be controlled using embedded C program. If you press a button to take a photo with your digital camera, then micro-controller will perform the functions essential to capture the image and store it. This article presents basics of embedded systemsmicro-controller consists of many ports to construct the embedded C programming tutorial. [Read more…]
Most of the applications of embedded systems require keypads to take the user inputs, especially in case where an application requires more number of keys. With simple architecture and easy interfacing procedure, matrix keypads are replacing normal push-buttons by offering more inputs to the user with the lesser I/O pins. As a Human Machine Interface (HMI) keypad plays a major role in vital microprocessor and microcontroller based projects and equipments. Therefore, this article gives you a brief idea on matrix keypad interfacing with 8051 microcontroller. [Read more…]
The advent of fast growing technologies makes users to have high security systems with electronic identification options. These identification technologies include ATM and other intelligent cards, user IDsand password based systems, and so on.But,unfortunately these are unsecure due to hacker attacks, thefts, and forgotten passwords.In spite of all these shortcomings and malfunctions these systems are still prevailing; however, the biometric or fingerprint authentication based identification is the most efficient and reliable solution for stringent security.

The Basic requirement of security can be achieved by designing electrical or mechanical locks that are designed with one or a few keys, but for locking a big area many locks are required. Basically traditional locks are heavy and are not protective as they can be broken down easily by using some tools. Electronic locking systems are preferable over mechanical locks, to resolve the security problems that are associated with the mechanical locks. [Read more…]
Nowadays crime rate is increasing day by day as it is quite evident from the fact that thefts have become a matter of routine. The vehicle thefts particularly cars may incur huge loss on the part of the amount invested on these vehicles. Therefore, the need of the hour is a better anti-theft control system that can be implemented by using several technologies like GPS, GSM, GPRS systems. This article provides some of the microcontroller-based projects for the car security system that are intended to protect the cars from being stolen even if they are parked in the parking area.

Programmable switching of loads is a necessary option for the process industries to operate sequential processes that eventually lead to end product. In this era of industrial automation, most of the industries are automated, and such automation requires that the loads to be operated should be done in a preprogrammed manner. And also during the load shedding process, the utilities department performs the loads to be turned on or off for particular periods mainly during power recession seasons. [Read more…]
